Thank you very much for the reply. That is the exact demo and source example I was reffering too. The demo does not post to Twitter and when I execute the source example it authenticates but when I post it gives me 404 not found request back.

My guess is that the request uri in the dll might not be used on Twitter anymore and might need to be updated, not sure how to troubleshoot this one.

On the forums at Twitter they say I am likely using an endpoint which has been turned off.

If someone could perhaps confirm this demo and source example is working I would appreciate.
